If you have access to '12+ WR450 CO FI Setting (obtained by using the FI "diagnostic" tool) .vs CO Gas "Sniffer" readings data, please post it up.
I'm looking for this type of data:
(These are *BOGUS* Data here, just being an example)
FI Setting CO Reading
You should probably include some info about any changes (from "OEM" standard) about the motor, exhaust, and / or intake systems that are on the cycle being tested.
Sadly, I have none to offer. I do not have access to a gas sniffer.
I am able to offer the use of a diagnostic tool to someone who *does* have access to a gas sniffer, no charge, if they were willing to post up their findings here. Say, in increments of 1, from -5 to +15 (to +20?) on the FI diagnostic tool setting, and give the result in CO%.
